Title: Water carves and molds the Earth
Summary: This lesson examines the power of water and how it shapes the earth. The students will already have background on weathering. Through a guided notes part of the lesson, students will take notes and learn about the power of water and the process of erosion and deposition that occur because of it. They will also learn about the features that are formed by water erosion above ground and by ground water. Students will examine the layers of sediment to make connections to the features that are formed by water through a short lab that is from their Prentice Hall Physical Science text books.
Objectives:
  • Students will understand the difference between deposition and erosion
  • Students will examine the features formed by water erosion
  • Students will understand ground water erosion
  • Students will through the in text quick lab will examine the layers of sediment and compare and contrast their observation to what would be found in nature
Materials:
  • clay
  • gravel
  • sand
  • small plate
  • jars with covers
  • stop watch
  • spoon
Instruction:

Opening:
  • Explain to the students that this is a picture of a meandering stream in South Greenland.
  • ask the students to take 3 minutes to brainstorm the reason this stream is shaped the way it is or why it meanders?
  • Have the students share their answers, if no one has identified the driving force behind the shape of the river then explain.
  • Explain to the students that the lesson they will be learning today will have to do with the power of water to carve the Earth.
  • timing = 5-10 minutes
Middle
  • Pass out the class notes to the students
  • Explain to the students , as you had mentioned in the previous class, today we would be discussing what they read for homework and filling in the blanks in the class notes
  • Call on students to read a part of the notes and give an answer to what the blank in the notes should be.
  • Continue to call on different students until all of the notes have been reviewed and filled in.
  • Instruct the students to turn to page 714 in their test and that they all are going to do a small mini lab in which they can see the layers of different sediment and make connections to the notes they just completed in class.
  • Ask the students how the arrangement of the sediment plays a big role in the effect water has on shaping the Earth
  • timing = 30-35 minutes

Closing
  • Instruct the students to pour out the water without pouring out the sediment and instruct them to place the sediment into a bag at the side of the teachers desk.
  • Have the students return to their seats and explain about the project they will be starting during the next class that deals with adopting a body of water and describing it and it's environment.
  • Explain to the students that their homework is to read section 23.4 and that they would be required to know the information for a class discussion about glaciers and erosion during the next class.
  • timing = 5 minutes
